In the early-mid 90's Florida instituted vehicle inspections.  Only lasted a couple of years and then disappeared, not sure why.  Be interesting if this testing really comes back.

Larger tip increases the probability of the electrons actually choosing to hit the tip and not leaking up the handle.

You know, I've thought the same thing. I recently used it to set the HV on the Tek 465 and it was close quarters and I had to be real careful I didn't cause a flashover. I'm considering putting some sleeving on about 3/4 of the tip but you would still have to be careful or you might exceed the flashover point of the sleeving itself.

But does it really need 2" of exposed tip?

Sleeving should improve it in my mind.
